UNITED STATES PETER KNUPPEN, OF MILWAUKEE, WISCONSIN.

SOFA-PILLOW.

Application led March 6,

To all whom it may concern.'

Be it known that I, PETER KNUPPEN, a citizen of the United States,residing at Milwaukee, county of Milwaukee and State of Wisconsin, haveinvented new and useful Improvements in-Sofa-Pillows, of which thefollowing is a specification.

My invention relates to improvements in sofa pillows.

The object of my invention is to provide a spring cushioned sofa pillowwhich will retain its shape without being hard or unyielding at theedges and corners.

In the following description reference is had to the accompanyingdrawings in which,

Figure I is a view of my improved pillow with the covering and fillingremoved on one side to expose the frame and springs. Fig. 2 is atransverse sectional view. Figs. 3 and 4 are detail views of modifiedforms of construction at the frame corners.

Like parts are identified by the same reference characters throughoutthe several views.

The sides of the frame are composed of resilient wire, preferably in asingle piece, and bent zig-zag to form successive inward and outwardbends l and 2 respectively, all in the same plane or substantially so asshown in Fig. l. At the corners'the wire may be bent inwardly in a broadopen bend 3, as shown in Fig. l or it may be wound in a flat coil 4 inthe common plane as shown in Fig. 3 or in a spiral coil 5, as shown inFig. 4. The flat orms shown in Figs. l and 3, are, however, preferred ashaving the least tendency to noise or to produce hard spots in pillows.

The corners are connected diagonally by cords 7 and the sides areconnected by cords 8 at intermediate points 9. The cords S preferablyextend straight across and at the crossing points of the diagonal cords7. Spiral springs l0 are located with their axes transverse to the planeof the frame wire and cords. The cords are preferably connected withthese springs, and other cords 6 may be employed as stays for thesprings if desired. The structure thus formed is provided with a casingll of any suitable fabric, between which and the outer cover l2 is afilling composed of a layer 13 of coarse material, (preferablyexcelsior) anda layer 14 of finer material, (preferably cotton). Thefilling covers the margins of the frame as well as the sides, and asthev frame is free to yield in all directions the presence of themetallic parts will be little noticed. For example, if the pillow issubjected to a direct pressure between two corners on the same side, thebends in the wire will readily yieldand approach each other, and reactto their original position as soon as the strain is removed. The wirewill also yield as readily to lateral or twisting strains.

Speccation of Letters Patent.

Patented Nov. 5, 1907. 19o?. serai No. 360,819.

While I have shown and described a square pillow it will be understoodthat it may be made round, square, star shaped, or of any desiredcontour.

It will be observed that the frame forms the pillow margin and that thebends extend outwardly and in- Wardly with reference to the centralportion of the pillow. The filling and the coiled springs serve ascushioning devices and separate the upper and lower walls of the coverbetween the frame margins. The cords are secured to the inward bends ofthe frame wire, and as two sets of these cords extend divergently acrossthe the springs at the crossing points they not only assist in holdingthe springs in position but also assist in holding the frame against anytendency to twist or buckle.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is,

l. A pillow comprising an open marginal frame composed of resilient wirebent into zigzag form, with the bends extending inwardly and outwardlywith reference to the central portion of the pillow, a covering, andcushioning devices separating the upper and lower walls of the coveringbetween the frame margins.

2. A pillow comprising an open marginal fralne, composed of resilientwire bent into zigzag form, a set of coverings for the frame, packinginterposedv between the coverings, anda set of coiled springs within theframe disposed with their axes crossing the planes of the frame and ofthe individual bends of the frame wire.

posed of resilient wire bent into zigzag form, a set of coverings forthe frame, packing interposed between the coverings, and a set of coiledsprings Within the frame disposed with their axes crossing the planes ofthe frame and of the individual bends of the frame wire, together' withsets of cords extending divergently from the inner bends of the framewire to the respective ends of the coiled springs and arranged to serveas stays for both the coiled springs and the frame.

-l. A pillow comprising-an open frame composed of resilient wire bentinto zig zag form, a set of coverings for the frame, and suitablepacking interposed between the coverings, all of said bends in the wirebeing substantially in a plane common to the general outline of theframe.

5. A pillow comprising an open frame composed of resilient wire bentinto zig zag form, a set of coverings for the frame, and suitablepacking interposed between the coverings, said wire being coiled at theAcorners of the frame and the several sides being formed integrally.

In testimony whereof I ax my signature in the presence of two witnesses.
